Intel i3-2115C AV8062701064700 Fiche De Données

The processor includes enhanced power-performance technology that routes

interrupts to threads or cores based on their sleep states. As an example, for energy

savings, it routes the interrupt to the active cores without waking the deep idle cores.

For performance, it routes the interrupt to the idle (C1) cores without interrupting the

already heavily loaded cores. This enhancement is mostly beneficial for high-interrupt

scenarios like Gigabit LAN, WLAN peripherals, and so on.

The Execute Disable Bit allows memory to be marked as executable when combined

with a supporting operating system. If code attempts to run in non-executable

memory, the processor raises an error to the operating system. This feature can

prevent some classes of viruses or worms that exploit buffer overrun vulnerabilities

and can thus help improve the overall security of the system. See the Intel

IA-32 Architectures Software Developer's Manuals for more detailed information.

Intel

®

 Device Protection with Boot Guard can help protect the platform boot integrity

by preventing execution of unauthorized boot blocks. With Intel

®

 Device Protection

with Boot Guard, platform manufacturers can create boot policies such that invocation

of an unauthorized (or untrusted) boot block will trigger the platform protection per

the manufacturer's defined policy.

With verification based in the hardware, Intel

®

 Device Protection with Boot Guard

extends the trust boundary of the platform boot process down to the hardware level.

Intel

®

 Device Protection with Boot Guard accomplishes this by:

•

Providing hardware-based Static Root of Trust for Measurement (S-RTM) and the

Root of Trust for Verification (RTV) using Intel architectural components.

•

Providing architectural definition for platform manufacturer Boot Policy.

•

Enforcing manufacture provided Boot Policy using Intel architectural components.

Benefits of this protection is that Intel

®

 Device Protection with Boot Guard can help

maintain platform integrity by preventing re-purposing of the manufacturer’s

hardware to run an unauthorized software stack.

Intel

®

 Device Protection with Boot Guard technology availability may vary between

the different SKUs.

Supervisor Mode Execution Protection provides the next level of system protection by

blocking malicious software attacks from user mode code when the system is running

in the highest privilege level. This technology helps to protect from virus attacks and

unwanted code from harming the system. For more information, refer to Intel
